The City manager has seen his side fall five points behind Manchester United in the Premier League title race after slipping up against Stoke City and Sunderland in their last two league games.
It leaves Mancini’s side facing the prospect of finishing the season without a trophy following their premature exits in the Champions League and FA Cup.
And the 47-year-old acknowledges that his reign at City could come to an enforced end at any stage.
“I started my job two-and-a-half years ago and from that moment I think we have improved a lot as a team, as players, as a club,” said Mancini.
“I think this is important when you are at a new team. When you choose the job you should know anything can happen any moment but I don’t have any problem with this.
“When you work hard for your job and you improve for your team, I think this is important.”
Mancini joined City after a four seasons as Internazionale manager, where he led the San Siro outfit to three Serie A titles and won the Coppa Italia twice.
The former Lazio boss was brought to City in 2009 to replace Mark Hughes at Eastlands, and Mancini is adamant his working relationship with chairman Khaldoon Al Mubarak remains positive.
“My relationship with Khaldoon is fantastic,” he added.
“I can say if he sacks me at the end of the season or next year – I don’t know – I can say every manager that works with Khaldoon is very lucky. Khaldoon is a really good man.”
